SH'UTTERING DEVICE FOR CASTING WALLS.

Application led November 21, 1925.

This invention relates to improvements in shuttering devices for building concrete walls in situ in which the shuttering boards or the like are spaced, positioned and kept in place by a plurality of vertically arranged supports which can be successively advanced as the work progresses, and it has for its object a form of supporting unit which can be selectively and continuously utilized for building both cavity and solid walls of different thicknesses. Another object of this invention is to enable a maximum height of wall to be built before a new adjustment of the shuttering devices is necessary. A

further object is the provision of means for securing` the vertical supports to the transverse members and for enabling said vertical members to have transverse movement relative to the transverse members in order to free the. vertical members from the shuttering boards without disturbing the wall. A still further object is to facilitate the release and withdrawal of the inside shuttering boards in building cavity walls.

I attain these objects by the construction illustrated in the accompanying drawings which illustrate a construction of the device which can be used for building solid walls of four different thicknesses and cavity walls of two diflerentthicknesses. In these draw- ,ings Figures 1 and 2 are views in plan and elevation of one of the cross plates of a supporting unit suitable for supporting the shattering boards for casting cavity walls of 131/2 inches Aand 18 inches thickness, and solid walls of L.L1/2 inches, 9 inches, 13% inches, and 18 inches thickness. Figure 3 is a view in cross section of one of the supports, Figure 4 is aview in cross section of another of the supports, Figures 5 and 6 are views in elevation and in plan showing the'use and application of the improved supporting unit in casting a 131/2 inch cavity wall. Figure 7 is a similar broken view showing it when casting'an 18 inch cavity wall. Figures 8, 9, 10 and 11 `are similar broken views showing the. device employed for casting solid walls of litl/2, 9, 131/ 2 and 18 inches respectively.

Throughout the views similar parts are marked with like numerals of reference.

The shutter supporting units each consist of Ia plurality of Hat plates 1, three rods 2,k

3 .and 4, and a plurality of wedges 5. The

rods are for convenience all of uniform or approximately uniform length and as far as possible of the same width and thickness.

In each of the plates 1 are four apertures 6, 7, 8 and 9, the first and second of which are located at the ends of the plate and the aperture 8 is located at a predetermined distance from on-e of the. end apertures. The width `of each of these apertures is slightly in excess of the thickness of the rods 2, 3, and e, so that they can pass freely through said apertures and the length of said apertures exceeds the width of said rods to the extent necessary to receive the wedges 5 and to allow the rods to come free of the shutterine boards when the wedges are withdrawn.

he other aperture 9 which is located between the aperture 8 and 4one of the end apertures 6 or 7 isof approximately the same length as the other apertures and its width is approximately the same as its length for a purpose that will hereinafter be apparent.

' ln the. construction illustrated in the accompanying drawings the distance between the aperture 9 and the aperture 6 is 11/2 inches plus the thickness of two of the shuttering boards 10, the distance between the aperture 9 and the aperture 7 is 9 inches plus the thickness of two shuttering boards, and the distance between the aperture 8 and the aperture' is 131/2 inches plus the thickness oftwo shuttering boards.

For casting solid walls'l/Z, 9, 131/2 or 18 inches thick two rods 2 and 3' are employed which engage respectively the'apertures 5 and 9,' 6 and 8 or 6 and 7 in the plates 1. For casting cavity walls 13 or 18 inches thick three rods 2, 3 and 4, are employed which engage respectively with the apertures 6,' 8 and 9 or 6, 7 and 9.

In operation the plates 1 are allowed to remain in the wall toy support the rods and as the work proceeds said rods are raised vertically step by step according to the distance apart the plates 1 are spaced and as said plates 'are no longer required they are knocked out of the wall before the concrete has set.

In building` cavity walls the. rod lV is only locked to the upper plate 1 and in order to release thein'side shuttering the rod, after the wedges have been withdrawn, is turned through an angle of 90 as shown in dotted lines in Figure 6 so as to bring its Width transverse to the plate. This frees it from the shuttering boards and allows it to be readilyvvithdrawn after Whichthe shuttering boards can be lifted out one byy one either directly by hand or by the use of a hooked rod.

t Will be understood that in constructing cavity Walls the Width of the cavity can within the limits be determined either by the Width of the bar employed to engage the apertures 9 in the plates or by the'thickness yof the shattering boards employed or by both in combination. Beyond these limits one or more additional apertures 9 must be provided. l
